GHI's .NET Micro Framework modules, such as EMX and ChipworkX, provide WiFi support through RS9110-N-11-21-01 WiFi module. This allows for real "Socket" connection over WiFi for example with EMX module you can open up to 127 TCP/UDP sockets simultaneously with SSL security. This is not a simple WiFi-Serial bridge commonly used on simple embedded systems.
This module from Redpine's Connect-io-n™ family is a complete IEEE 802.11bgn WiFi client device with a standard SPI interface to a host processor or data source. It integrates a MAC, baseband processor, RF transceiver with power amplifier, a frequency reference, an antenna, and all WLAN protocol and configuration functionality in embedded firmware to provide a self-contained 802.11n WLAN solution for a variety of applications.
- Compliant to 802.11b/g and single stream 802.11n
- Does not require any WLAN driver on the host processor
